Ok well for one thing bad choice on the PSU. Here is a list of good and bad PSUs
Unofficial PSU Ranking List (What's the best PSU to buy?) - Hardware Discussions - FiringSquad Forums
For a budget good choice in processor. I have the same one, works great, decent speed. I also bought it for a friend that I built a computer for. Also the graphics choice is fine. I think that was the one I bought for my friend also. As for the RAM, you will need to decide that once you pick out a motherboard. CD drive is fine. Hard drive is fine also. Actually you know what I will do, I will post all the parts that I built for my friends computer for you. You can change parts if you want and everything. But its probably right in the price range that he wants. And it was a decent computer to.
*EDIT* Ok here are all the parts.

So there ya go. Feel free to change parts out. Though these parts make a nice little computer. About the Power Supply. In that PSU list I gave above, it says that Rosewills are not recommended. Yet that is the second I have bought and they both have worked great! I have had mine for about a year now with no problems. So really I think they are decent lower end PSUs. By no means if you are building a $1000 computer should you get a Rosewill, but for a lower end computer I think they are fine. Oh and also, that case is really really nice. Great air flow, and allows for like six fans or so.
